bacterial immune system? how developed / nil !? - recombinant bacteria tolerance? (Dec/19/2007 )

me has a verrry basic question.. some how missed knowing this..

how is and how good is a bacterial immune system..?? how does it work?

also, why don't bacteria chop off the proteins that r synthesized within them.. with recombinant DNA.. ?

lemme know plss...


bacteria have a protein called H-NS, which recognises and deactivates DNA from other organisms.
i dont' think it's an "immune system" rather a mechanism.

as for why they don't attack the proteins we stick inside them... magic? tongue.gif i wrote it down in a note book somwhere... and never bothered to learn it. have to try and look that one up.
